The development of aluminium complexes implementing redox-active ligands has the potential to significantly broadened the reaction chemistry of the element through expansion into redox-based chemistries. Herein we report the synthesis of aluminium coordination complexes implementing redox-active nitroxide-based ligands. We will specifically discuss the coordination chemistry of N-tert-butyl-N-(2-R-pyridyl)hydroxylamines ( R pyNOH; R = H and CH 3 ). Synthetic details and characterization (1H and 13C NMR spectroscopies, X-ray diffraction) data for the aluminium complexes supporting one, two, and three R pyNO - ligands will be presented. The electrochemical characterization of the complexes will also be presented. Finally, we will discuss the reaction chemistry of the complexes with various Lewis acids
